Synthesis

The synthesis of PoF6 via the reaction

210Po + 3 F2 → 210PoF6

was attempted in 1945, but the attempt was unsuccessful. The boiling point was predicted to be about −40 °C.[2]

208PoF6 was probably successfully synthesised via the same reaction in 1960 with the more stable isotope 208Po,[1]: 594  where a volatile polonium fluoride was produced,[3] but it was not fully characterized before it underwent radiolysis and decomposed to polonium tetrafluoride.[4][5]
